Narratives and notes on this MT103 SWIFT Message

As usual, there is more in this MT103 SWIFT message than meets the eye. The following narrative and notes allow to get a deeper understanding of the message content.

Narrative and note 1 (Main purpose of this MT103 SWIFT message)

The Sender (BNPAFRPP) is asking Receiver (PNBPUS3N) to debit sender’s account and credit account of the Bank (OCBCSGSG) indicated in tag 57A.

This indicates that Sender and Beneficiary customer’s Bank do not have direct account relationship in the currency of the transaction (USD).  Otherwise the sender would send the message directly to the beneficiary customer’s Bank.

Narrative and note 2

The ordering institution (Tag 52D) is provided in the MT103 SWIFT Message. This means the ordering customer is not customer of the Sender. BNPAFRPP sends the MT103 on behalf of the ordering institution 52D:BANQUE DELUBAC ET CIE.

BANQUE DELUBAC ET CIE is a small bank that has an agreement with a major bank (BNP PARIBAS) for the processing and settlement of currency transactions. BANQUE DELUBAC ET CIE can then use the correspondent network of BNP PARIBAS.

Narrative and note 3 (Account relationships)

  • Sender (BNPAFRPP) has an account relationship with Receiver (PNBPUS3N) in USD currency.
  • Receiver (PNBPUS3N) is correspondent of both sender (BNPAFRPP) and Beneficiary Bank (57A:OCBCSGSG) in USD currency. PNBPUS3N can debit BNPAFRPP account and credit OCBCSGSG account.
  • Ordering Customer account (:50F:/01234567890) is opened with Ordering Institution (52D:BANQUE DELUBAC ET CIE).

Narrative and note 4

Details of charges (Tag 71A) is SHA. The charges are shared between Ordering and beneficiary customer.  Sender pays charges to ordering bank. Beneficiary pays to receiving bank.

It is always interesting to see how much can be said about an MT103 SWIFT message like this one. But the message has not reached the final destination yet (57A:OCBCSGSG). The receiver (PNBPUS3N) must forward it to the beneficiary’s bank. What are the differences between this message and the next one (that PNBPUS3N will forward to OCBCSGSG)? What does that message contain and what are the meaning of the different message elements? These questions will be answered in the next article.

    Nice, you can structure out of MT103 format as well with Incoming and Outgoing SWIFT 103 payments

    • Jean Paul December 17, 2018 at 3:20 pm #

      Yes. Depending on the direction, if the payment is sent to the SWIFT network or receive from the SWIFT network, the block 2 content is different. See the block 2 page.

    From the ordering institution was this message sent as Mt101 to sender ?
    if there was no direct relationship between sender and actual receiver bank(where account of beneficiary exists) then why receiver correspondent was not used ?
    I am new to payments can you please provide clarification over the above questions ?

    • Jean Paul December 25, 2018 at 9:12 pm #

      First question: The ordering institution received an instruction form its customer through MT101 or through other means like E-banking, Teller and so on.
      Read my articles about MT101 to understand how that message is used.
      The actual transfer is carried out with an MT103 message between financial institutions.
      Second question: The receiver correspondent is used. However, in this particular case, sender and receiver correspondents are the same.
      I hope it clarifies a bit.

    Tag53a consists of sender correspondent , Tag54a consists of details about receiver correspondent , but that tag is empty in the message ??

    • Jean Paul December 30, 2018 at 11:12 pm #

      Yes neither of the tags is present in the message, because it is a serial message. Please read the article about Serial and cover payments.

      • aditya January 2, 2019 at 8:06 am #

        I read the article , i want to ask why receiver correspondent is not stored in Tag56a.

        • Jean Paul January 2, 2019 at 9:44 pm #

          Ok I got it. It is simply because the receiver of this message is the receiver correspondent itself.
          So no need to mention it again in the message. He knows he is the receiver’s correpondent and what to do with the message.
          I hope this helps. 🙂

    What is the role of 56 in an MT103? That is, who does it pass on the payment to, 54 or 57 or 53?

    • Jean Paul January 28, 2019 at 12:08 pm #

      F56 sends to payment to F57. See article about Serial and Cover payments.

    Why is tag 57 (bnf bank) an optional field (as per SWIFT standards)?

    • Jean Paul February 11, 2019 at 1:22 pm #

      Hi Chris,
      You find the response in the SWIFT standards. Under the usage rules of Field 57a: Account With Institution, you read the following:”When field 57a is not present, it means that the Receiver is also the account with institution.” So if you send the payment directly to the receiver that is also the Account With Institution, no need to mention the field 57. Let me know if you have further question.

  6. Chris February 11, 2019 at 4:16 pm #

    Thank you. That makes sense.

    However, the sender and receiver info is usually not located in block 4. So the operator creating the message should be aware that the receiver and the account with institution are the same…..correct?

    • Jean Paul February 11, 2019 at 8:39 pm #

      True. Sender and receiver info are not provided in the block 4. Operators should be aware of it definitely even if well designed payment engine softwares can be of great help in guiding the end users.
